Application lei September 26, 1923.` Serial No. 664,897.

My invention relates to urring units useful for securing plastic reinforcement to the wall sheathing of frame buildings, although also useful for other purposes.

l A An object of the invention is the provision of a disk-like spacing element formed by wrapping a strip of paper ak suicientnumber of times around the forward end of a driven element, the spacing element opera# l tively slidable on the driven element for cooperating with a side arm on the latter for clamping the reinforcement therebetween when applying the latter to the wall sheathing.

A further object is the provision of afspacing element i formed of librous material having a certain amount of iexibility so as 'to -forin a seat for the reinforcement wire thatkis somewhat yielding and whereby 39' the spacing element will not injure the reinforcement by cutting|` or crushing it in case the 'latterisorced-down thereupon recessively by the excessive driving of the driven element. c

A still further object is the provision of asolid spacing element formed ofV yielding fibrous composition and having a lower `flat side adapted to seat against the face of the building paper, in case the latter is applied to the wall sheathing of the structure, and

firmly bound against said building'paper by the driven element,y whereby water or moisture will be prevented from penetrating or leaking between said spacing element, and a5 building paper.

A still further object is the provision of a fnrring unit comprising a driven elementy projecting axially through a disk-shaped spacing element, the latter having upper and lower at sides disposed in parallel relation,

thereby providing the spacing element withA a lower seatingl surface approximately equal in dimensions to the` area of its lower side, and an upper wire receiving surface ap'- proxifinately equal to the area of its'upper sidel andextending from., the sides of said driven element laterally in any direction to the rim of the spacing element.

ylVith the foregoingjand still furthe-r objects and purposesl in view which will ap'- pear as the description proceeds, myfinvention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed7 it ab being understood that changes in the precise embodiment( ofv the vinvention herein disclosed can be made Withinthe scope of what is. claimed without departing from theispirit of the invention. l

Fig. 7, showing method of forming the spacing disk yby Wrap-ping the paper ribbon around the driven element. 'n l Referring to the drawings in detail, throughout which like reference characters designate like parts:

The numeral 1 designates a representation n of the wallsheathing lof aframe building,

which forms the backing or base against which is adapt-edto be spread anfouter coat of plastic composition, 2 the furringunit, and 3 a wire` forming a portion ofthe plastic mn reinforcement, the latter comprising, preferably5 wire cloth commonly known as poultry netting.

The furring unit 2 embodies adriven element 4 rcomprisi ng a shank member 5 having 1,05 its upper end bent toone side to forma downwardly projecting yside arm 6, and a spacing element 7 ,comprisin .av strip of paper 8, which f isi` wrappef lliatways around the shank member 5 in continuously 1m receding coils disposed in tightly Wound order in a common plane, with the lirst'coil upon the periphery of the shank, the second coil on the iirst coil, and so on throughout the length of the strip until. la disk-like elcment of proper diameter is formed.

lt is preferable that the paper, previous to Wrapping it around the shank 5, be subj ected to a treatment of heated bitumen pitch or the like, as a preservative against disintegration from atmospheric dampness or dampness directly applied by the spreading thereon of the wet plastic materials when the latter is operatively applied to the wall. The said treatment being` intended to also provide sufficient adhesive to the sides of the paper strip so that the several coils into which the paper is rolled in forming the spacing element will adhere to each other and thereby remain in a tightly rolled-up condition on the shank.

After the paper has been tightly and permanently rolled onto the shank 5, it is preferable to immerse the unit in hard-drying asphaltum varnish or the like, so as to impart thereto a certain amount of rigidness and to cause it to adhere to the shank and become normally locked thereon against accidental movement when the units are packed in the bulk into receptacles for purposes of transportation or the like, or when handled as when applying them operatively to the sheathing boards, but vertically slidable on the shank by 'disrupting the adhesive seal between the latter and the spacing element When the latter is disposed against the Wall sheathing and the shank operatively driven thereinto.

It is preferable to have the spacing element factory-built onto the forvvard end of the driven element and carried thereby (see Figs. 1 and 2), and slidable vertically to the upper end of the shank against 'the resistance of the adhesive only when the furring unit is operatively applied to the wall sheathing for securing the reinforcement.

It is frequently desirable to dispose building paper against the wall sheathing before applying the furring units and reinforcenient. T he building paper coacts With the Wall sheathing in forming a base for the plastic composition. In case of the application of the building paper as aforesaid, it will be found that the paper spacing'disks of my furring unit, being of yielding quality, may be forced thereagainst Without cutting or injuring it in the leasthowever eX- cessively the shank may be driven. It is common occurrence in applying` all metal furring units, particularly those having sheet metal spacing devices, such as the devices disclosed in Patents 383,952; 1,311,932 and 1,435,429, as Well as the lVagner-Behm device shown in Engineering Newsof Aug.

5, 1915, over building paper, .to not only cut and damage the same, but all these devices fail to effect definite or precise furrmg for ythe reinforcement for the reasonA thatwhen the shank element is accidently driven eX- cessively, 1t causes the comparatively narrow `edges of the sheet metal spacing elements to penetrate the wall sheathing to a more or less degree.

lt is to be understoolil that, while l prefer te roll or wrap the paper strip directly on and around the shank of the driven element in forming the spacing element, yit can be formed separately and the shankafterwards projected through a central opening therein.

It is further to be understood that I do not desire to restrict myself to the particular method-described of temporarily locking the spacing element on the forvvardend of the shank by adhesion, but instead, if desired,l the spacing element may be retained on the shank by tightly embracing it and held against movement by the friction of the one element bearing against the other.

It is obvious that any number of the furring units may be employed in securing a section of the reinforcement.

To apply my device to the Wall sheathing, the furring unit is projected forwardly through one of the meshes of the reinforcement from the outer side and the point of the shank engaged with the sheathing with the body of the shank disposed alongone side of one of the Wires of the mesh (see Figs. l and 2), the shank is then driven into the sheathing until the side arm engages said wire from the upper side and forces it down firmly upon the upper end ofthe spacing element and thereby permanently holds it thereagainst. The plastic composition being adapted to be spread on the Wall'sheathing and on and around the reinforcement and the protruding portions of the furring units. v f

I claim: l

1. ln means of the character described, building paper adapted tovbe secured to a support, a yielding spacing element formed of fibrous composition and having a fiat side seated against the face of said building paper, and means projecting through Said spacing element and said building'jpaper and adapted to be projected in said support for binding said spacing element firmly against said building paper whereby moisture is prevented from penetrating therebetween to said means belenT said spacing element.

2. A furring unit comprising a driven element and a substantially cylindrical spacing element, said spacing element formed of a strip of paper boundy on and around the shank ofsaid driven element, to normallyresist removal therefrom. v'

3. The combination with a driven element having a side arm at its upper end, of a sis' spacing element encircling the forward end of said driven element and normally locked thereon against vertical movement relative thereto by means of an adhesive element applied to both said first named elements, said adhesive element adapted to rupture and thespacing element adapted to slide vertically along said driven element intooperative co-operation with said side arm when said driven element is operatively projected a proper distanceV in a support, said spacing element formed of fibous material.
